RE: What's the meaning of virtual POP ?

Different providers use the term with different definitions, but this is how we use it: At Level 3, a VPOP is a POP that we operate under someone else's license. For example, we have VPOPs in a number of markets throughout the Asia Pacific region, including countries like China, Vietnam,

Re: Cisco Nexus vPC-VOIP Issues

Hi Santosh Likely it's disabled arp across broadcast (assuming both servers are on same broadcast domain). One can comment on it after looking at config of the port. I have seen similar case in some hosting providers who run shared vlans across customers and they block direct traffic among those

Re: Managed global low latency network with any to any connectivity

Thanks for the input everyone :) @Mikael, Roderick, Unlike HFT and financial markets, the applications we have to support are not microsecond-sensitive. Infact, a +-10ms difference from 'least possible' is acceptable provided that the connection is stable. So basically I am looking for most

Re: What's the meaning of virtual POP ?

The key is really that it could mean different things for different providers, although I would agree that the gist is that the location is enabled to look and feel like a POP without the provider installing the full complement of requisite hardware. A provider I worked at in the past, for

RE: Managed global low latency network with any to any connectivity

The real issue in the request is that this person is looking for any-to-any connectivity which will require either a single L2 switching domain or a L3 routing domain. While waves, SDH, and SONET might be your layer one transport there are two major factors that are going to affect latency and

RE: Managed global low latency network with any to any connectivity

This is kind of the holy grail of networks you are looking for. You have to be a lot more specific than global to really shop this. As far as I know (and I have looked a lot), there is not one network that can get you to most countries with the best performance. For example, China is a

Re: Managed global low latency network with any to any connectivity

There are standard routes and there are low latency routes that serve mostly traders. The latter charge a big premium. He said the lowest possible latency. That is a specialty market where the SLAs are in microseconds, not milliseconds. Many carriers have a division for ultra low latency.

Re: Managed global low latency network with any to any connectivity

So you want point-to-multipoint which means Switched Ethernet. But ultra latency traders don't want the extra latency associated with Switched Ethernet. And they dominate the demand for ultra-low latency. Regards, Roderick. United Cable Company From: NANOG

Re: Managed global low latency network with any to any connectivity

AT's AVPN product (Layer 3 VPN/"MPLS") does any-any routing and constantly changes L3 hops for the best pathing. I've used the service at a few jobs and the product itself is quite good. Dealing with them for things like MACD's can be...frustrating. We've never had a location they couldn't
